Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586462, here are decompositions:

151 + 31586311 = 31586462
181 + 31586281 = 31586462
331 + 31586131 = 31586462
409 + 31586053 = 31586462
499 + 31585963 = 31586462
613 + 31585849 = 31586462
883 + 31585579 = 31586462
1009 + 31585453 = 31586462

Showing the first eight; more decompositions exist.
